Multi-User Display Audio Correction Based on Hearing and Position
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional display apparatuses only consider the hearing characteristics of a single user when adjusting audio output, failing to satisfy multiple users with different hearing abilities and being inflexible with user positioning, leading to unsatisfactory sound experiences for all users.
Innovation Solution
A display apparatus that captures the faces of multiple users, measures their hearing levels, and adjusts audio output through multiple speakers based on calculated average and weighted hearing levels, taking into account both hearing characteristics and user positions to optimize sound output for all users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the display apparatus corrects sound according to the hearing characteristic of a single user, then the sound is optimized for that user, but other users with different hearing characteristics experience poor sound quality
Solution Approach 1:
The patent segments the audio output into multiple channels corresponding to multiple speakers, and applies different hearing level corrections to each channel based on the position and hearing characteristics of individual users. This allows each user to receive optimized sound through their preferred speaker while other users also benefit from the corrected audio.
Solution Approach 2:
The patent applies local quality by adjusting the hearing level correction differently for different speakers based on user position. Users closer to certain speakers receive stronger correction for those speakers, while users farther away receive less correction. This creates localized optimization of sound quality for each user-speaker combination.
2Device complexity
If the display apparatus uses a fixed position for sound correction, then the correction is simple to implement, but the sound becomes unsatisfactory when users change position
Solution Approach 1:
The patent implements dynamics by making the hearing level correction adjustable based on real-time detection of user position. The system automatically adapts the correction parameters when users move to different positions, ensuring optimal sound quality without requiring manual reconfiguration or fixed positioning assumptions.
3Reliability
If the display apparatus outputs sound optimized for users with poor hearing, then those users can understand the audio, but users with good hearing may find the sound too loud or uncomfortable
Solution Approach 1:
The patent segments the audio correction into multiple speaker channels and applies individualized hearing level adjustments to each channel. This allows users with poor hearing to receive enhanced audio from their preferred speakers while users with good hearing experience appropriate volume levels from all speakers, preventing discomfort.
Solution Approach 2:
The patent applies local quality by tailoring the hearing level correction to each user's specific position and hearing characteristics. Users with poor hearing receive stronger correction for speakers they are closer to, while users with good hearing receive more balanced correction, ensuring audio accessibility without causing discomfort.
